Abstract

The invention discloses a theft protection disc lock having a lock core capable of idling, which comprises a lock body and the lock core inside the lock body. The lock core is divided into a front lock core and a rear lock core, wherein, the front lock core is provided with a plurality of groups of locking plates, a locking side column, a slider, a cam (a groove) and a groove (a cam) which are respectively arranged on the slider and the locking side column and are matched with each other, and a slider reset spring arranged between the slider and the end wall of the side column; the rear lock core is provided with a locking pin chute, a locking pin arranged inside the chute, and a locking pin reset spring arranged between the end wall of the locking pin chute and the locking pin. The elasticity of the locking pin reset spring is greater than that of the slider reset spring, at least one of the locking pin and the locking side column adopts a slope to be in contact with the other, and steps and locating gaps for stopping and rotating the rear lock core are arranged on the tail part of the lock body. The lock can effectively prevent being unlocked through picking and twisting the lock core violently and reduce the mutually openable rate of the lock.

Description

technical field [0001] The invention belongs to mechanical locks, and relates to an anti-theft tumbler lock whose lock core can rotate idly. Background technique [0002] In terms of locks, the blade lock has been the most widely used product. Among the existing blade locks, there is a kind of lock that adopts multiple groups of two overlapping locking plates on the lock core, and the locking plates have V-shaped grooves, and the lock core is controlled by the cooperation of the locking plates and the locking side columns. on and off. This structure better solves the weakness of traditional mechanical leaf locks that are not resistant to technical unlocking and picking and twisting the lock cylinder. For its structure, please refer to the ZL200320115784.X patent document. But this lock still has the problem that it is difficult to resist destructive forceful unlocking. If you use a strong enough unlocking tool to forcibly pry the lock cylinder, you can twist the bolt fixi...
